This is the circuit of Full Wave Rectifier. I only just want to know this Circuit is working Right or wrong. Want suggestions from your side.

At the moment the earth is on the positive side, reverse all the diodes and that will correct the problem. To use this as a power supply place a capacitor across the output of the bridge, somewhere between a 100uf and 4.7mf depending on your load and or the amount of ripple you can put up with.

How can I tell that the earth is on the positive side? There are 3 ways. 1 the diodes in the bridge point to the positive side. 2 if you look at the waveform between the two diodes on the side away from the earth you can see that it is upside down. 3 when you put a capacitor across the bridge, it will show you the polarity of the voltage.

Simpler to just reconnect the earth to the other end of the resistor. However I do see why you've gone for the other approach since it's nice to have the positive at the top of the circuit - it just seems right :-)

Yep...
